This standing stone is located within an enclosed field on a south facing slope. It is 1.25m tall, 1.1m wide and 0.8m deep. It is oriented NW-SE and tapers to a point. The stone has many quartz inclusions.

The standing stone is believed to be of religious or ceremonial significance and to date to the Bronze Age (c.2300 BC - 800 BC). This example is recognised for its group value as the middle component of an alignment of three standing stones. The monument is likely to retain significant archaeological deposits and enhance our knowledge of prehistoric ritual practices.

The area to be scheduled comprises the remains described and an area around them within which related evidence may be expected to survive. It is circular and measures 6m in diameter.
